Abstract
There are many kinds of fungi related to allergies in different environments. The authors have worked on fungal distribution and biological findings of allergenic fungi in the home for the past decade. This paper describes the distribution of fungi related to allergy in the air (outdoor and indoor), housedust, air conditioning filters and fungi contaminating households such as in the bathroom, kitchen and damp areas. Airborne fungi in the home peaked in spring and autumn in most years in Japan, while house dust fungi did not change year-round. The dominant fungi were mostly Cladosporium, Penicillium and Aspergillus in those environments and other predominant fungi differed depending on the surroundings. Their distribution is determined by the lifestyle of each household.
